[REQ] Removing range estimation from the TBT

[LukeFF]

I got this idea from a new mod being done for SH3:

In essence, the TBT was like its German counterpart, the UZO, in that it only fed bearing info to the TDC - it was not a rangefinder.

Now, with that said, is there any way this can be modded into the game, or are the targeting tools inseparably linked between the periscopes and the TBT?
