I somewhat doubt it. Do other vendor top 3070 card versions like Strix from Asus/Master from Gigabyte/Supreme X from MSI have same cooler & PCB and do their LC blocks list compatibility also for 3070 cards?
One needs to submit pic of one's 3070 PCB or Palit/Gainward needs to answer AC requests for PCB drawings (which they don't look like are very keen to).
Then again .. if it's same cooler and on 3070, which is of way lower TDP, imho 3070 is in way less need for LC, as cooler that should be able to dissipate double the heatload, on lower end card should be fine as is cooling/loudness wise, and thus even if upcoming block won't be compatible with it, less of a loss.
