i actually use 6.5% C15L in my standard IPA, so for my eyes, your grist looks fine.
your hop schedule is piddly.
i've not really seen many folks adding hops for an ipa at 35, 30, 25, 15 - was that something you read or were trying to duplicate?
I can offer my strategy for hopping if you'd like, but what you have is so starkly different from what i do, you may be looking for something particular and I wouldn't want to steer you away from that.
EDIT - on further reading your original post, i guess that is what you are looking to go after. Its not something I would be interested in brewing, but it seems like you are after something in particular, so I guess just brew it and see what comes of it. Maybe its exactly what you are after.
