It would not have the same power. There are many ideas in SICP that trigger breakthrough moments (metacircular evaluator, church encoding, code is data / data is code, tower of interpreters, emergence through abstraction) that would easily be seen as gimmicks in Python, because they transcend the hastily-put-together nature of Python.

Lisp was discovered and evolved by geniuses.
