I take these words of yours to be an elaboration of a part of your "guiding philosophy"
They're not, actually. ...
So you 're claiming your guiding philosophy to not be a guiding philosophy ... well
Not at all.
I'm claiming only that no particular philosophy is necessary in order to see the simple logic of the "conventional" assumption. It stands or falls not on what my philosophy is, but on the logical consequences that it, itself, entails.
And anybody can see those. All you have to do is understand the premise.

One would not have to believe any part of my philosophy in order to be driven to the same conclusions. ...
Since I don't believe anything of your philosophy I am not driven to your conclusion.
But it's not MY philosophy at all.
I don't believe in "conventionalism" about ethics. But "conventionalism" itself determines what follows logically from it. If you say, "Good and evil are conventional," then what that entails flows from that statement...nothing else.

"Conventions" are trivial, contingent, temporary and non-binding.
Judgements like "good" and "bad" are conventions, contingent, temporary and non-binding.
Actually, I would argue they're not. But I agree that conventionalism
has to assume that's true, so we may continue. Let's go with your supposition, not mine.
That doesn't deter people to commit themselves to such judgements and to follow guidelines that are conventionally judged as "good".
They can indeed "commit" themselves to particular judgments or guidelines. But since they think that "good" only means "conventional," then what they are really saying, logically, is "The judgment I've chosen to commit to is the same as is conventional among those people I like."
What they can't say at all is, "My judgment on X is
actually good." "Good" has no particular meaning in that sentence, for them. It's just another way of saying "conventional."
Rationality is relative
"Rationalizing" may be relative. But rationality itself is not. And logic is not.
In technical language, philosophers say that logic is
formal -- meaning it doesn't require you to believe in a particular worldview in order to use it. Anything can be plugged into logic, just as any numbers can be plugged into mathematics, and logic will issue the logical results.
Logic shows that for a conventionalist, "good" cannot have any meaning. Nor can "bad." That's because all goals, goods and bads are all presumed to be merely "conventional," by definition of the position. If one doesn't believe that, one is no longer a conventionalist.
And it's logic, once the supposition of conventionalism itself is plugged into it, that demonstrates that.
