A program modifying DOS's internal data which could effectively link in
new UMBs is easy enough to write, provided that the kernel's handling of
the UMA is compatible enough to that of the MS-DOS kernel.

The BIOS doesn't know anything about cluster sizes. Maybe you mean sector

All versions of DOS I know require the use of a TSR (like FDAPM, or
MS-DOS's POWER) to idle correctly, or of a program that does the idling
itself (I don't know any COMMAND.COM version that does so). However, as
the flawed call usually will simply be called by idle-unaware software, an
