How dangerous is this modified exhaustion compared to other harmful conditions?

In this question, I asked about the ramifications of monsters causing exhaustion:

How dangerous is exhaustion?

The answers concluded, that this would generally be very risky and dangerous.

I therefore decided to limit myself to a reduced threat version for the time being, which has the following modifications:

1. Limited effect

A target only gains exhaustion levels this way up to three levels. Any excess levels that would be caused this way are not applied.


2. Easy recovery

Taking a short rest or casting lesser restoration removes one level of exhaustion gained this way. Taking a long rest or casting greater restoration removes all levels of exhaustion gained this way.

How does this compare to other harmful conditions, such as stunned or paralyzed? Could I replace a stun or paralyze effect with one level of this reduced threat exhaustion and maintain a similar power level of the monster?
