Hi Jeremy,
Such a hybrid would certainly be possible (though getting novel
crypto into bitcoin is a large task).
You refer to an "order or magnitude" increase in pubkey and signature
sizes, but signatures of even 64k wouldn't make much logistical
difference to the LN. Giant pubkeys might be a logistical issue, though
using the bitcoin trick of referring to them via their RIPEMD160 should
work there, too.
Cheers,
Rusty.
