Can this replace a K4645 Tank

This question is from Highline 1.6 GPF Single Flush Toilet Tank Only in White

December 9, 2015
The one I have has flushmate pressurized unit within it. It was a unit that is on recall and could decide to replace the parts sent to me, but I read there is some risk of tank exploding, so rather not risk it.

The bowl connected to though say 1.4 GPS or less - it is back outlet vs floor outlet. I would like to keep the bowl intact and only change the tank as would be a bit of a pain to change out the bowl.

Also, if not this tank, then which one would work?

Thank you in advance.
