I have an 435 MHz simplex link radio on a 440 MHz repeater.  I have my controller not holding PTT for a hang time on the link port and obviously no courtesy tone either.  The other repeater I am linking to is set up the same way.  This makes the link very seamless.  You cant even tell that its coming through the link except that I made the courtesy tone different for the link radio.   All that was needed to accomplish the in band link was a Band-Pass cavity on the the link radio to provide some RF isolation and a little vertical seperation for the antennas.  
 
By the way, multiple links can be accomplished by simply adding a link radio on the same link frequency to each repeater in the system provided that all the link radios can hear each other.

Yea, even in the same band.  UHF repeater with a UHF remote base.  The repeater is on 442 with the remote base on 444.  It's linking to another repeater about seventy miles away.  We let each repeater ID on it's own.  The repeater TX PL tones are COS operated so that the PL tone is only transmitted when some one is talking plus a short hang time.  That way at the other end through the remote the only time you hear the ID from the other repeater is if it's IDing over or while someone is talking.

Just out of curiosity and because it's more on-topic - how many people
have RB's of some sort on their repeater systems on the list, and to
which band(s)?
