No room for Combat Archery. That will have to wait until the level cap is increased.
Epic Destiny enhancements are still up in the air. Right now, Shiradi Champion Tier 5 is still significantly better than Machrotechnic for dishing out damage. So I'd only go Machrotechnic Tier 4. Shadowdancer Tier 3 provides a ton of utility and damage with 6 sneak attack dice, Evasion, Dimension Door, Reflex saves and Max Dex Bonus increases.

1 Battle Engineer Unlock Potential

PRR and MRR are the soft spots in the build, especially if you don't have the past lives.
As ranged, you’ve got inherent “don’t get hit” defense from melee. It’s probably worth dropping 1 Evo DC and 2 Rune Arm DC from Arcanotechnician core 5 to pick up Deflect Arrows from Vistani Knife Fighter to deal with archers. Coupled with 35% Dodge, that’s excellent defense — assuming you aren’t getting one shot by mobs in higher reaper levels.
MRR will matter for non-evadable damage, such as the electric floors in Master Artificer, chaos damage in Killing Time, etc. I would probably put points into MRR in the Grim Barricade tree rather than PRR to reach 100 MRR cap.
Caveat: I haven't built this on Lamannia or in a planner, so there may be mistakes. But you get the general idea how things will land if you follow this build.
