Yes all radios can fail but those on 72 are mire likely to because they have more fragile parts in addition to the interference problem.
You have my permission to do what you like. Its your airplane.

Personally I have yet to experience a radio failure due to a CDI spike in both 72 Meg and 2.4 Gig. But experienced it plenty on 27 Meg. On the other hand, everyone can see that 27 is 72, backwards, so that's the reason.... LOL

In fact the 2.4 systems I know of put out less than 0.1 watt.Also the atmospheric loss is much greater at 2.4 than it is on 72. The savings grace on 2.4 is spread spectrum systems are capable of up to 40db processor gain. That is the same as increasing the transmitter power output 4 orders of magnitude. If our systems were capable of that much processor gain it would be equivalent to a TX power of 100 watts. Our systems are not capable of that much processor gain but they have enough to make it work
Another factor to consider is most 72 equipment has been manufactured some time ago. Electronics dont last forever. Electrolytic capacitors in those units dry out and quit working.
