"Ramming Reapers with Cruisers"

We've seen how well cruisers vs. Reaper goes in ME1.

"detonating lost planets while Reapers were harvesting the population, or destroying some Mass Relays while Reapers were in the blast radius"

There's no guarantee that either of these strategies would work. Especially the latter.

"But we're not discussing what Bioware will and won't do with ME3."

We're discussing the ending of ME3. Thus, it is what BioWare will or won't do with ME3 and they've made it clear that Refusal ends in defeat.

"SO now what happens when the current cycle makes synthetics? The whole thing starts all over again?"

Have you played the Leviathan DLC? Unless a race like the Leviathans arises, the same thing happening all over again is unlikely.

"Bioware has already added an ending for refusal. Bioware can still add a caveat for your Paragon/Renegade status for refusal."

They already have variations based on your Paragon and Renegade status: Paragon: You lose. Renegade: You lose.

Why should there even be a difference in Refusal based on Paragon/Renegade morality? Why should one be favoured over the other?

"I think the star child was just assuming everyone will be happy with forced synthesis."

The Catalyst seeks to prevent organic/synthetic conflict. Through Synthesis, all life is preserved and there is no longer a division between organic and synthetic life; thus the problem it was created to address will no longer exist.
