It is possible, but it isn't easy.  NST cores are shunted.  That is, small bundles of laminated iron are tucked into the core windows between the primary and secondary coils.  These iron shunts add a large leakage inductance to the NST, resulting in fairly rigid current limiting.  Removing some or all of the shunts will increase the output current.  To remove the shunts, the NST must be released from the block of tar or resin it's potted in.  This can be a messy, time-consuming process.  Also, the depotting effort sometimes damages the fragile NST windings.  It is do-able though.  Many members of this list have done it successfully.  Search for "depotting" in the WWW.pupman.com archive for more info.

A Geissler tube is not an X-Ray source.  It is a glow discharge tube filled with rarefied gas--similar to a neon sign.  So no, you can't make X-Rays with it.  To make X-Rays, you need a Crookes tube, a cold cathode X-Ray tube, or some other sort of "hard" vacuum tube.  Assuming you employ a proper tube, NSTs do develop enough voltage to produce soft X-Rays, according to Wiki:
