I want to program an AVR attiny2313 with my AVR ISP MKII

So I built a header that connects to a breadboard where I want to burn the firmware to the attiny via ISP,

so my question is,

I have a design that uses an external xtal of 16Mhxz

but I dont have space on the actual protoboard for the ISP header, so can i upload the firmware with out a xtal [will configuration of fuses work?] and then use it the proper external xtal?

Thanks!
