In other words, you are asking, "is there a way to cheat?"

Again, part of what makes a coin have value is the effort required to get it. Crypto coin algorithms are created to be exceedingly computationally and/or hardware intensive for that reason. If someone want to mine a coin they MUST put some effort into it by getting and running the hardware needed. It should not be a surprise that coins that have high value like BTC require expensive miners. Find a flaw in the code that can be exploited to make a coin easier to mine and:
a. you would for a time destroy the value of the coin
b. the blockchain networks would eventually cancel the effect of cheating by adjusting diff higher
