That makes sense, but it would make 48 slightly longer. LTA
might not want to play with long-haul services, although 48 is
quite direct and was extended in the past.
As for the new Bedok North service, looping at Bedok North St 2
would be good. Also, great if it connected Bedok South Rd, then
there would finally be a link between Bedok South Rd and Bedok
North. (Yes, 46 technically links the two estates but it will only
serve Bedok South Av 3, but a well planned route
nonetheless).
It does not make sense to extend sv 48 to CBP. There is already
sv 47 that is parallel right from Parkway Parade to CBP. The
loading on 47 needs to still pick up, for 48 to go CBP.
