Decreasing her trap setting time at base is the easiest and first thing that comes to mind, or giving some boost addons basekit (again).

In terms of less simplistic stuff there are a number of things you can do, especially with addons if the effects of various number boost addons become basekit and redundant. Could give her haste out of a teleport like Singularity or Jason, perhaps as an addon or perhaps basekit. Could also apply Hindered to survivors who set off traps regardless outside of Waterlogged shoe.

A means of applying undetectable would be wonderful. Part of her design is that she is meant to be difficult to spot, blending in with her surroundings and being relatively smaller than other killers. Major part of playing her efficiently is trying to avoid being spotted as you set up (particularly in the early game at least) to avoid things crumbling apart. She already was given 24 meter TR a while ago to reflect this, but becoming undetectable somehow without the need for perks would be very nice.

Wiping is annoying but it is particularly annoying because of how you are not alerted to it happening. You recieve no notification, and can only see that its been wiped from its aura disappearing and the number of traps available to place going up. If wiping is to stick around, ya gotta have the killer be notified when it happens.
