A question: Can Peter mimic blocking power of the Haitian (and add Haitian's blocking/mind erasing power to his power pool), or will Haitian block all of Peter's powers (including his mimic power)?

i think it would just cause problems between the both of the. like they both would loose their power or it would hurt just like when matt parkman was trying to read peters mind and all they got was static

i think peter would absorb it but since he wouldnt know how  to use it the haitians power would just cancel anything out

Depends on how poweful the Haiton's power is:

If he nullifies Pete's power, then he would be unable to absorb it.
If they somehow both share the power, they'd probably cancell each other out.

Well yeah the Haitian would cancel out Peters ability so it would become a street fight. Depending on who can kick whos butt first woul be the winner. Probally Haitian because he has training, Peter is too used to using abilities.

if peter ever encounters the haitan and his powers arent blocking peters than he would have it
