Hey Nerd, Unfortunately these suggestions arent likely to be implemented as;
The donor zone stalls are simply a higher xp yield, and not meant to be used to gain GP. Its unlikely this will be changed as theirs plenty of other methods for thieving.
As for the tool belt, the tools are not meant to be your highest tier tool, This would be unpractical. The tool belt is used to fill basic and bronze tools only as a base in case you dont have your higher tier tools on you. This is a feature in RS3 and is also unlikely to be changed
Thanks for the suggestions!,
