By all means, replace them. All that heat is power that would otherwise be transmitted. If the resistors actually are falling apart, the amplifier might become unstable. The originals are fine.
There is no advantage to using nichrome wire in the inductive part of a 
parasitic suppressor.

After I purchased my AL-82 I discovered that someone had replaced the
original parasitic suppressors with the nichrome wire/3 resistors per
unit type.  I have had no problems but the resistors become VERY hot
at even 400W on 10M and have started falling apart.  At powers higher
than 400W I actually smell them!

Was there anything wrong with the original suppressors or did someone
just get carried away and replace them because it seemed the “in”
thing to do?  I am thinking of making a set of “originals” and
installing them so I can occasionally operate 10M without fear of
having those resistors burn out.
