I can help out with templates of the stuff I've done for my P1 costume, though I can't guarantee that I'll have everything you need for a complete outfit. So far, I've done the shoulder armor and the codpiece. I'm reworking one of Vinmanmac's templates for the shoulder bell, and I'm also going to be doing my own designs for the upper leg armor and the shin armor. If time permits, I'll try to do the right shoulder plate and the left bicep armor.
No guarantees on timeliness, though, since I have just under three weeks to get my costume done for our local convention.
