Source IP persistence maps the client IP to a pool name and member IP:port. So it won't work if the pool members are different. Browsers will ignore a cookie set for one domain (example1.com) when they requested a different domain (example2.com). Just to clarify, are the two FQDNs different subdomains (sub1.example.com and sub2.example.com) on the same domain? If so, the cookie idea would work if you set the domain on the cookies to .example.com.
Another option if the domains are different would be to do manual tracking of the client IP to pool member mapping using a subtable for 10.1.0+. Subtables are global objects which are accessible from any virtual server's iRule.
