help installing ps2 into mame cabinet

[alexbpb]

ive completed my mame cabinet and was wondering, if i wanted to add a playstation2 to the  cabinet, is it possible to wire the ps2 pads to the arcade controls if theres is already an ipaq wired to the controls?  would there be a conflict?  and also, is there some kind of pre-soldered kit with wires already soldered onto a ps2 pad? (i have no experience with soldering and dont trust myself to even try) if not, i would be willing to pay a byoac member any costs for parts/labor in making me such a kit. thanks for any and all help in advance, and hope to hear from you guys soon thanks!
