Oh no!!   Don't redefine \cr .

It is a TeX primitive that denotes the end of a line in tabular
layouts. You will have weird difficulties with any tabular
material that you try to typeset.

(\cr - mnemonic for  <CR> = carriage-return )


Rule #1 for macro-writers:

   Do *not* use 1-letter or 2-letter macro names,
   unless you really, really, really know what you
   are doing; and even then, you should choose something
   longer that better describes the purpose of the macro.

I don't know what "keep the latex mapping" means.
What kind of errors do you get?

Try changing your macro-names, to see whether that helps.

e.g.  \newfontfamily\cree{BJECree}e


But why keep switching?
If you only use the alternate font for words and phrases,
then take advantage of TeX groupings:

e.g.;
   .... in this sentence some {\cree words} are in
   {\cree a different font} whereas most is in
   the same {\cree basic} font. ...


Or use a macro with parameter, as follows:

\newcommand{\altfont}[1]{{\cree #1}}

   .... in this sentence some \altfont{words} are in
   \altfont{a different font} whereas most is in
   the same \altfont{basic} font. ...


This way you only ever set the main font once,
and the switches into the alternate font are well-defined.
