Would there be any problem with making the stack grow in the opposite direction

The direction the stack grows is usually fixed by the processor architecture, at least in all CISC-style processors. For example in the x86 family there are several common instructions that automaticlly push data to the stack or pop it. Making the stack grow in "unnatural" direction would require somehow working around their behaviour. Maybe you could do it but it certainly would impact performance and introduce extra complexity.
