As I said before, my all time favorite is the Delta Gundam. For my part, as a pilot, I was kind of the opposite of you. My aim was bad, but I always did really well at dodging incoming fire, weaving my way in close, and laying into people with my beam sabers. I customized the Delta a bit ingame in SDGO, and ended up painting it in a crimson and navy color scheme I'm rather fond of, as well as equipping it with a custom logo of a triangle divided in half by a one-way line, prompting me to call the resulting customization the "Delta Ray Gundam," because geometry and linguistic jokes. As such, I've always wanted to try building an actual Gunpla based on that - probably a Delta Plus with elements of some SEED mobile suits like the Destiny, since I'm a sucker for built-in weapons packs and Wings of Light. It would no doubt forfeit the transformation gimmick, but keep the iconic elements of the Delta's appearance while adding a whole load of multipurpose armaments and possibly some particle-based gimmicks to go along with them. However, it'd take a lot of hard work to make into a reality, since I'd probably be using Master Grade kits to build it in order to get the maximum amount of detail. MGs, however, are notoriously hard to kitbash.
In the mean time, though, I've been working with some more basic HG kits as practice.
Specifically these two. Probably going to be trying to modify the Doga's skirt armor to incorporate the sheaths for the Astray's anti-ship swords. Then I might try adding parts from the Miss Sazabi to replace the clunky leg units and add more thrusters. That, or I could replace the backpack with the Gunner ZAKU Warrior's, and give it a huge gun. Either way, then I'll custom paint the whole thing and maybe even try it out in the Build Fight System to see how it holds up.
