[R] mixed models with ordinal independents

are there potential drawbacks in the use of rank (ordinal) variables as 
predictors in a "linear" mixed model for continuous dependents?

I am trying this approach to create mixed effects models independent of the 
(monotonic) transform of the independent variables. The use of rank 
transformed independents seems the logical choice to me.

Thank you for any feedback,
