That sounds similar to something in New Haven. When WB started in 1995, WTNH-TV (ABC) channel 8 of New Haven carried the early 2 hour block on Saturdays at 11:30 PM ET. WTVU-TV channel 59 of New Haven signed on a couple of months later. The WB program block was moved there. They would then up their power and change their call letter to WBNE-TV (Warner Brothers New England). Today they're WCTX-TV (MY) and are the sister station of WTNH-TV.
