Can't hurt. I have the kit that replaced both ends, one end adds a heat
sink, and gives 'handles' that help protect the knobs and display from a
fall, etc. Then the plastic cover that snaps into the handles. Works
well.
I run FT8 and Winlink VARA (which if you are sending a message has an
even longer transmit cycle than FT8 on weak signals) and it seems to do
OK.
Keep it out of the sun, that helps, too.

I recently acquired a KX2 and use it on CW only.
I noticed that it does get warm. Are the aftermarket heat sinks
needed?
