--This is a plan I had to rearrange the data and expand tables to allow for a large amount of levels, worlds, levels in worlds, and such... (the thing in brackets is the memory address it deals with/overrides), the asterisked items I didn't implement.

I also rewrote tables to map the World A-D overworld levels to 10-1F (level numbers mean nothing in my new system, since DB/5C/BA are overridden by table) as well as got rid of the cheap trick Nintendo put in to access those higher overworld levels, though this is only to make the existing SMB2j data work in the system, any user would be able to make any level number, any level type, for any world, arranged in whatever way they like.
Old world/area tables for A-D:
A 20 3F 45 21 6A
B 22 3F 08 23 6B
C 24 25 26 6C
D 27 28 29 6D
New Table for World A-D:
A 10 29 45 11 6A
B 12 29 08 13 6B
C 14 15 16 6C
D 17 18 19 6D
There are level number assigning possible for 128 levels (00-7F), the original game allows for 32 of each 4 level type(overworld (20-3F), underground (40-5F), water (00-1F), castle (60-7F)), though with ASM hacks you can get rid of the level type restrictions, and even expand it to 256 levels (you'll have to redesign the E row exit pipe sprites though, shoudlnt' be too difficult). As for assigning these to the world/area scheme, the world/area tables only allow (this is for SMAS SMB, not SMAS SMB2j.. actually applies to NES ver as well) space for 8 worlds and 36 levels spread across the 8 worlds (4 of those levels are actually x-2 entrance levels in the original game, though you can change them to non-entrance levels to create a 5-level world, and adjusting the world pointers give for a bit more freedom), as you'll see in my previous[, much too long of a] post, I allowed room definition of up to 256 worlds (yes, a little overkill ) and up to 256 levels to be spread across them.
