Hmm. There are several things which could be done.
Firstly, the key for the inv request doesn't need to be the node key. You can use an ephemeral one, so that's one possibility (ofc your node has to honor it, but that's an implementation detail).
Alternately, fields 250-1000 are not covered by the signature. This would allow an extension to say "put an amount, signed by Bob, in field 255". Of course, clients would need to understand that that should use this amount field, not the normal one.
Also, having a mechanism to pull funds gives me the "credit card vibes" ick, but maybe that's just me...
