Can we use ALTQ and PF to modify packets which acts as a bridge in my testing environment?

It's not clear to me what it is you're tryint to achieve. PF with ALTQ
is certainly capable of traffic shaping.  

The FreeBSD Handbook's PF part recently grew a bit, and it might even
have material or references to point you in the right direction -
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/firewalls-pf.html 
and look for section "30.4.6 PF Rule Sets and Tools"
