I wouldn't take that bet, as there is definitely a market for silly, to which 5E has always been open for business. Adventure Zone, Acquisitions Incorporated, etc.
For what it's worth, the Acq Inc C Team, which is considerably less silly than the main-stage A team, had its own Spelljammer arc this season. There were many over-the-top, bizarre moments, but it was mostly not played for laughs.
