I believe, there is no harm in allowing a cleric to get those maneuvers with feats... in my opinion just a normal trip is usually a 60-40 chance it works... which is still not so good. And if the cleric can gain advantage due to roleplaying, more power to him. I really want the figter to be able to take the healer feat and heal a bit. So I believe, it is fair.
In my opinion the expertise dice mechanic should be the fighters stick... it is not: hmmm... how do I get advantage on the roll, but instead he says "I di get advantage (and maybe even add the d6 to the higher roll). It is his expertise, that allows him to do those tricks with advantage, whenever he needs it (a limited times per encounter) and then have a reasonable chance to achieve his goal... advantage +d6 should be nearly guaranteed to win the opposed check... even against a giant his odds are reasonable.
So yeah:
normal guy: disadvantage -> fighter (2/encounter) normal + 1d6
normal guy with feat: normal -> fighter with feat (2/encounter) advantage +1d6
I believe adding 1d6 to a roll and gain advantage on top is a powerful ability, that does not reach too far out of bounds, but increases the odds so much, that it can be seen as an extraordinary ability.
