125-200cc Backwards updated plastics/tank

I'm looking at my options with my 99 WR125 and I've seen the mods needed to go to newer, readily available body parts. I like the generation I have, but there is nothing available at all. Even used shrouds are super rare. I see the previous gen, up to 94 has brand new shrouds available aftermarket. I found a 94 WXC125 tank and can get the shrouds so, how bad is it to get it on a 95-99 frame? I'm guessing the seat is different too as the 94 seems to have a raised rear tank surface. Dang it, I just put a new foam & cover on the 99 seat, maybe it'll fit the older pan?

Uncharted waters here or has it been done?

Thanks.
