Probably. You can, in principle, run Solaris as dom0, in which case it'd have
direct access to the video hardware, which might be useful to you. I'm not
an expert at Solaris on xen so I couldn't say that much more... I don't know
if USB passthrough would work on Solaris, which could be a problem.
The other alternative would be to run Linux as dom0 and run both Solaris and
windows as domUs. That'd probably get you lower display performance since
you'd be running through the virtual framebuffer, though it really depends
what exactly you're trying to do!
The Qemu device model used by Xen supports USB device passthrough to guests
such as Windows in principle, although I've heard varying reports of success
with this in the past. What kind of devices do you need to pass through the
USB port?

Sharing folders would best be done using something like CIFS / Samba, since
there's not a safe way of directly sharing disk accesses between Windows and
Solaris (not commonly available or free, anyhow!). You could restrict this
sharing to a totally internal virtual network on the system if you wanted.
Possibly worth noting that other virtualisation platforms could also handle
something like the setup you describe, and they may also offer different
tradeoffs regarding CPU performance, graphics performance, ease of sharing
folders, etc.
Cheers,
Mark
