Risk of neck warp with hybrid strings?

Disclaimer: I can't do a search at the moment, but I have looked on the last couple of pages and can't see any similar threads so here goes:

I've currently got a hybrid set of strings on my Warwick bolt-on neck bass at the moment, consisting of:

G - 035 D'Addario Prosteel
D - 055 D'Addario Prosteel
A - 075 D'Addario Prosteel
E - 100 DR Hi Beam
B - 125 DR Hi Beam

I really like the sound this is giving me, but would this set up (extra-light strings on top, medium-light strings on bottom) risk warping my neck due to uneven tension?

They've been on about 5 days so far with no noticeable difference, but I'm wondering about the long term effects. Being a Warwick neck, it's fairly chunky, but it is quite an uneven load.

I wouldn't think it would bother anything.. for a while I used .040 .055 .075 .095 .120.. and by a while I mean 6 months. No "bad" change in the neck at all.
