ME/IR before CPL

[powdermonkey]

Hi all

Due to the fact that my school does the CPL in a twin ( lack of single complex), one of the possible avenues after ATPLs is to do the ME rating, do my 40hrs in FNPTII for the multi IR, and then do 15hrs in the twin. Now I will have Me/IR, and should be comfortable in the twin and my skills well sharpened by the time I do my CPL training and Test.
Are there any pitfalls in this way of doing things?
Anyonelse done it and could give advice?

Thanks
