Yes, absolutely.

I think you first need to come up with a way to deal with ipw2[12]00,
dealing with that kind of devices is priority number one before the
devicescape stack can go anywhere. Once that is handled all software
MAC drivers in wireless-dev should be migrated to the device-scape based
stack.
After that we're in the right position to deal with last big step of
the merge:
a) deal with the userspace interface issue. Either rever to the single
network device and eth%d name interface (at least for the non-AP case)
so existing userspace won't know about the name underlying stack at
all or alternatively go through the painfull design process for a new
userspace interface. I think the first variant will be a lot easier..
b) do all the small compare and review work. See how different the interface
for software mac devices are for softmac vs dscape. See if any of the
old code should be reintegrated into dcape, port forward dscape API
changes to mainline to make merging more gradually. In the best case
we'd migrate the current mainline code fully to the finally dscape
revisited API so the new code really is a drop in, but I don't expect
that happen, the concepts are just too different. At least we should
try to make the interface diff as small a possible.
Once we're there I'm happy to help out on that step b) as much as I can.
