I'm not sure what kind of equipment you have on hand, but I have been toying with a modified co2 extract using non-super critical co2.
Basically if you have a decent pressure cooker that is rated to at least 1500psi (and multiple valves) you should be able to pump liquid co2 into it through the plant matter and then evap the co2 from the cooker's release.
It should make a low pressure "blast-method" hash but without the danger of using flammable solvent.
Of course you would reeeeeaaaallllyyy need to keep an eye on pressure and temp or your cooker might rip open.
