It is possible, using the right disk partitioning program, and the right
geometry remapping scheme.

However it would be insane under most circumstances to use 2GB FAT
partitions. The number of clusters in a FAT partition is fixed, so that
each time you double the partition size the cluster size, and thus the
minimum file size, doubles. For < 256MB the cluster size is a reasonable
4KB; it becomes 16KB for < 1GB and 32KB for < 2GB.

With a 32KB minimum file physical size you will be wasting almost all
your disk space unless your median file size is well above 32KB, which
rarely is the case.

You should really consider switching to OS/2 or Windows/NT (if you want
to remain in the DOS/Windows compatible set), whose _native_ file
systems (HPFS and NTFS) are much better suited to large drives, and very
much faster on those too.
