Yes you can. We do it (with a Keithley card) for our rats and it works
fine on the 16 channels (in Matlab, not tested LabView).

It depends on your time and money. If you have little time and a lot of
money, go for an EMG system. You'll get support and sometimes it's
important. If you have some time and/or little money (we have little
money), go an develop your system.
Be careful: I think that you will only be able to use your own system in
research-only areas. Don't try your system on real-human-patients: I
think you need some certifications (regarding safety etc.) for
Hope this helps you!
