Can't tell you about the F-162/Glide 8.5 combo, but I did sail the '07 Apollo quite a bit with the '07 7.5 Glide (rigged as full as possible) and it planed suprisingly early.
The light weight of the Glide, plus the super draft depth made me think I was on an 8.5 m2 Free race sail.
Combine this with the really early planing capabilites of the F-162 (or in my case the '07 Apollo) and you have a great combination for lighter sailors. Might work pretty good for heavier sailors as well.
Hope this helps,
