So I love packet combat - either as archery or spellcasting. A good tactical packet user is a lot of fun and very effective. I currently play a mid-level scholar w/ unified blow who only is not an archer because my other character is a low level fighter archer moving to spellsword.
If you are able to do a spirit forge, you might like going to a martial based bow build - either straight fighter or spellsword. It turns out 1.5 damage on profs really adds up in 2.0, with profs costing more as you buy more. 4 Profs, is +6 damage with a bow. (That extra 2 damage is the equivalent for 45 XP at 4 profs - so going fighter over rogue base is like getting 5 levels for free, after cheaper weapon skills.) For my archer, I swap back and forth between Longbow and Heavy Crossbow. If I know I'm doing only range, I use the heavy crossbow to throw 10's and big slays. If I think I might be in melee, I use Longbow and pull a shortsword as needed - but my goal is to not be in melee.
From there, you could go spellsword, but awkwardly Combine Strike works very poorly for archery. It doesn't synergize at all with the weapon profs so I'd recommend just skipping it. But Spellsword might be worth it for a mix of healing, buffing, and the occasional control spell -- especially if you can pick up battlemage's strike and/or empowered strike so you can use only one packet color (which when trying to manage a lot of packets, this ends up being a bigger deal than you'd think).
If you are going hybrid caster with bow and want to use spells for damage, I'd probably suggest going Adept and Unified Blow. 10x spell damage added on top of your normal damage is really good. It also lets you convert healing to damage -- without necromancy and for double damage, without having to manage multiple packet colors.
Since you gave us a build total, spit-balling some builds: (all of these include archery, two-weapon, 1H edged)
- Straight Fighter: 6 profs (13 w/xbow, 12 w/lbow, 11w/sbow, 8 1H), 5 slays (@140 w/ xbow;@105 lbow; @70 sbow/sword), 2 eviscerates, 5 parry, 2 resolute, 2 mettle. So total "burst" damage w/xbow: 1700
- Spellsword: 4 profs (10 w/xbow, 9w/lbow, 8w/sbow, 6 1H), 2 slays (@80 w/xbow, @60 lbow, @40 sbow/sword), 1 eviscerate, 1 parry, 1 resolute, 4/4/4 4/3/2 0/0/0 earth spells, 3 purify-strike. So total "burst" damage w/xbow: 660
- Adept: 4 backstabs (8 w/xbow, 7 w/lbow, 2/10 w/sword), 2 assassinates (@75), 4/4/4 4/4/3 2/1/0 earth spells. So total "burst" damage w/xbow: 1360.
- Rogue: 6 backstabs (10 w/xbow, 9 w/lbow, 2/14 w/sword), 5 assassinates (@150), 2 dodge, 2 evade. So total "burst" damage w/xbow: 750.

It may seem like fighter has more raw damage, but the adepts ability to not massively overkill or have a small number of defenses negate all its burst should not be undervalued. With that said, fighter has really good sustained damage -- throwing 12s all day will feel really good, and there is a lot of personal survival in that build.
Also, the Adept build is kind of bad. It is missing all the rogue defenses, because 185 is about the absolute _minimum_ to buy unified blow and I optimized it just for damage. In reality, it'd get much better over the next couple levels as it unlocked more spells, purify strike, and rogue defenses. If I was actually going to play it at that level, I'd probably drop a backstab and the assassinates to buy some defenses and utility - but either way its going to feel a bit weak for a couple levels as it ramps up. It'll likely feel amazing starting early/mid-20s...
The spellsword build has a lot of healing and utility in it, while still keeping a lot of sustained damage. Its burst may be low, but a lot of those spells can be healing, buffs, or control spells -- and unlike the adept you aren't wanting to memorize your spells to be damage. Its also in a solid place to buy up to becoming life capable. Or if you want to be more martial, to buy more offenses or defenses.
