If the goal is to have more seats:
Just get a proper LE/LF bus and install seats on platforms,
results in many seats, and only 1 or 2 pair of rear facing seats.
For example the MAN's Lion's city ü.
Note that all the seats are on raised platforms. (This is the low
floor version)
Another image:
The interior could look like this, the seats at the sides are on
raised platforms (but this is the low entry version, almost the
same)
If the goal is to create more standee
spaces:
Use a LF bus and leave the seats at the rear alone, while
changing the front the to the config of high capacity box bendies
(i.e. 1 seat on each side), or similar to kub to have parallel
seats facing each other.
The bus companies have to know their goals well, and not just
make a half-half version of each which fails both
purposes.
