Since I agreed with Mladen that it wouldn't work, I just had to test this.

On 8.1.7.3 on OpenVMS the "deallocate unused keep # " shrinks the initial extent.

It shrank a test table from 1m to 8k. I'm not sure why it chose 8k.

(db_block_size=4k, default initial_extent for the tablespace=64k)

I assume it would work on SYS tables as well.

(No sacrificial database that I'm willing to try it on.)

If you use "keep <int>" it will.

That will not do anything for the initial extent.
You may try with

alter table <table> pray intensely for the desired change;
