Yes, you would not want to lose the extra efficiency you get from the P condensor by using a smaller one than you can manage to fit in there.... Just keep in mind fluid dynamics when designing it...

After lots and lots of reading up on this when considering how to maximize my 240 AC... I found that this is THE RULE :

The Primary limiting factor in any ac design is AIRFLOW ACROSS THE CONDENSOR..... which is some coefficient of air heat transfer times the efficiency of your heat exchanger....etc...

So this is where you have to be sure you are maximized if you are to hope to realize any other improvements you have done to your system...
