I will amend my statement to reflect that you can
do it this way, if you consign yourself to spending a decent chunk of money in a short period of time.
But if, like the OP, you're rolling with a CCF pad and a USGI MSS (both of which are fully functional and will keep you plenty warm) but trying to find a way to make them fit into a frameless ultralight pack, your options are limited.
