SSTLaythe Spaceplane?

[Aanker]

Alright, so this is not the typical spacecraft exchange thread, in fact it is a bit like a challenge, but without the points, competition and leaderboards. Basically, with the new 1.0.3 fixes, is it possible to build an SSTLaythe Spaceplane that does what it needs to do without any staging or refueling? I've gotten one Spaceplane up with what is probably more than 2 km/s Delta-v, but it won't be enough to do anything other than skim through the Jool System I suspect.

Challenge accepted? Keep spaceplanes and similar creations specific to the task of reaching Laythe, since I dont want this to be a copy of the post your SSTOs here thread.
