Hello, and thank you for your reply.
They're actually owned by US West Communications (now Qwest), and
CenturyTEL (now CenturyLink), which recently bought all QWest DSL
related business.
I lease both blocks, and have ASN's for both.
My intention/goal is to route both blocks over the same GW (the 168)
The only solution I could come up with was to create a FreeBSD box to
serve as a Gateway, having it connected directly to the DSLmodem (external),
and simply have it assigned both an IP out of the 168 block, as well
as one from the 75 block. Problem is, I'll burn 2 additional addresses,
and create an extra hop to & from the network(s). :(

Thanks again, Julian Elischer for your reply.
