Might Republicans inadvertently help Democrats get the reconciliation bill passed? [View all]

They filibustered normal order legislation that would have raised the debt ceiling. If they hold firm to that position (or try to drive too hard a bargain in order to win enough of their votes to shut down a filibuster) it seems like the reconciliation process will become the only route left to keep the United States from defaulting on its debts. If raising the debt ceiling ends up in the reconciliation bill, it instantly becomes must pass legislation for all Democrats as time is running out on any other solution. It seems that if Schumer and Pelosi make a good faith effort to craft a bill that constitutes a reasonable compromise to the impasse that the reconciliation bill is currently mired in, that Democrats of every stripe, in both chambers, would be left with no choice but to back it to prevent the U.S. from defaulting. What am I missing here?
