IIRC, the Q55 would be extended to 170 St, The Q24 and 54 are cut back to Jamaica Station. It's really another case of robbing Peter to pay Paul. Merrick and Brewer are oversaturated with LTD service for lack of a better term. I think the Terminal (Jamaica) would be left to bare bones:
Q1-idiotically merged with a short turned Q5, with no service on Braddock
Q2-stays as is, loses overnight service, starts at Merrick and Archer
Q3-extended west to Jamaica Hospital
Q17-wacky merges with the Q25 and 88 among others, reviving the Q75 in the process
Q36-Merged with the Q110 and 112
Q43-extended to LIJ, no service west of Merrick
Q76/77-Merged with the Q27
Q6/8/9/40- All would start at Parsons
