I was wondering. I'm not a cryptographer, but can transactions be wired through another coin?

I assume you mean can txs be mixed offchain? This is essentially what CoinJoin a.k.a. DarkCoin attempts to do. The problem is that it requires masternodes to deal with the jammable two-step process, and the masternodes can (in theory) be Sybil attacked to reduce the anonymity.

So for ex: Monero devs make another coin purely for transactions called Mon. Once Mon has bloated enough, then they replace Mon with another coin called Mon2, etc etc, or Mon automatically does this for itself.

If you instead mean another block chain, realize it too has to be public viewable else it can't be secured with PoW.

Shouldnt that allow Monero to scale up to Visa levels if it can be implemented?

Or one can simply allow Moore's law to take care of the bloat problem.

If computation was the barrier, that is not certain because Moore's law may be ending:

The bloat issue impacts a lot of issues that have to do with how you can scale a coin in terms of popular features that will drive viral adoption.

As for blockchain pruning in its various incarnations it is a very bad idea because the "bloated information" is freely available at one point. This would allow large centralized holders to save this information, hoard it and then sell it at a premium to the average person. A simple scenario here could involve a legal dispute between and individual and a tax authority over transactions that are years or even decades old. The tax authority would have access to the old blockchain data while the individual would have to purchase that same data from a commercial data hoarder at a premium, thereby putting the individual at a significant disadvantage.

The cost of putting data on the internet and having it stored forever is nearly zero.

The issues with bloat are more dynamic in nature (e.g. propagation, tx speed, tx fees, etc). You wouldn't even begin to fathom these until you dug into programming an altcoin. So I won't even bother to detail them.
