Similar idiomatic expressions?

Question

Are there other similar idiomatic expressions or must one use the conventional gramatical constructs? For example:

If you were me... (Tú que yo?)

If I were him... (Yo que él?)

If he were you... (Él que tu?)

etc.

Hola MarkThe "yo que..." structure doesn't really work for when the subject is a different one to "I", so, for example to say "If you were me, what would you do?" you can't say "Tú que yo ¿qué harías?". For this you'd need the more literal "Si tú fueras yo, ¿qué harías?" or also "Si tú estuvieras en mi lugar, ¿qué harías?". The same goes for "If he were you...".Saludos
