I guess that would be a manual per-game option then? As I don't think that MISTer can know if there is monitor sync or not and thus "forced 60 hz" cannot be turned on as a fallback (eg. after x secs. without reaching sync).
Probable standard usecase: "I always want un-modified gameplay speed and correct audio pitch. But game XY has a troublesome horizontal signal length for my monitor and my monitor cannot sync at all. Thus I have to turn it on in the game options for that specific game".

A better way to do it for a CRT without the sacrifice of changing the cores clocks is just to adjust the complete display window to fit the video timing better.
I've done this for many cores in the past

See this example of how it would work for shouse
I built this to play around with https://docs.google.com/spreadsheets/d/1-dsPKfnta681RCE5VyKJGzNwRFjKvYVWYVJchHFKdE4/edit?usp=sharing
I think this is the location for it for the S18 core where H70 should be H83 to relax the timing for the line frequency to meet spec. E.g. 400 pixels vs 381 As per my calculations above. ** Though it wouldnt surprise me if HCNT END was what needed to change, not sure where the active window for the core is set
Note: HSYNC will need to shift as well probably between :8A- A6
E.g. Something like this:
.HB_START ( 9'h1ff ),
.HB_END ( HB_END ),
.HCNT_START( 9'h83 ), // it should be 'h50
.HCNT_END ( 9'h1FF ),
.VB_START ( 9'h0DF ),
.VB_END ( 9'h105 ),
.VCNT_END ( 9'h105 ), // 262 lines
.VS_START ( 9'hEF ),
.VS_END ( 9'hF3 ), // 4 lines
.HS_START ( 9'h08A ),
.HS_END ( 9'h0A6 ) // 4.8us measured in PCB
