VF-0D sure would be nice. I'm assuming your talking about the 1/72 Hasegawa. I'd say you should give it one more shot. Just take your time and enjoy the process of building.
If on the other hand, your talking about customizing a 1/60 Yamato. Then I would say, get someone else to do it. Especially if it's for $100.00.
When all is said and done, don't forget to share your pics.
