Could be feasible...Though, I'd probably opt for a heavy armor vers and explosives or hydros for detonation of mines...barrowing from the net, the weight needed to set off most is near 50lb. So, a hydro or explosive charge...possible seismic charge should work, realistically. metal...titanium. Nice job, though. My suggestions should be taken with a grain of salt. Good work.

I can see some conceptual flaws with that design but overall, nice work^^
