the design is stable with other mosfets. i've tried it with irf540n and irfb5615 and they're both stable.

do try the irs900d. you could just use 1n4148 for all the diodes except for the bootstrap diode nearest to the ir2110. 1n4148 should be easily available locally to most people. use 27-30 ohm gate resistor and you should reduce the mosfet and ir2110 heat.

also it makes much sense to run two of the irs900d bridged if you're thinking of drawing high power from them.

Increasing gate resistors to 30 ohms is not a good ideea, it will increase deadtime and quiescent current.
