If you want to play with house rules, that's fine. If nobody at your table has any problems with this, you are golden. This is a fairly common house rule and CritRole (Mercer) uses it quite liberally.
As someone who disagrees with critical success/failure on skill check rolls, I would like to better understand your position. I feel reliable talent and other abilities like it are diminished by this house rule. What would you say to me if I was one of your players and brought this up as an issue?
