Yes. I have one location which has 11 DSL lines and we're trying to get
4 more added.

That should work just fine as long as the DSL lines are from the same
ISP. With upload traffic, your router gets to decide which interface to
send packets out on so it can do whatever kind of load balancing you
want. The reason to use the same ISP is that many (hopefully most, but
unfortunately not all) will refused to send out packets from an IP
address that shouldn't be on their network. They do that to prevent DOS
attacks mainly, but it's just good practice in general.

Qwest will be happy to supply you with more DSL lines, as long as they
have facilities. For your two that shouldn't be an issue because you
probably have two phone lines coming into the building.

So yeah, it should be possible. To load balance incoming traffic you'd
need an ISP with a real clue. It would help in this case too, but you
can probably get away with it without.
