Can I transfer my HL LISA to a HL Stocks and Shares ISA without affecting my ISA allowance?

I have a Hargreaves Lansdown LISA and am concerned that the £450k limit may be too restrictive in the future as I am not planning to buy any time soon (and I am living in London). Since the withdrawal charge has been reduced to 20%, now would probably be the best time to make the change.

I also have a Stocks and Shares ISA that I would like to move the money to — can this be done without the LISA money counting against my annual ISA allowance?

UPDATE: Hargreaves Lansdown support confirmed they do not support such a transfer directly, however Skipton Building Society seem to support transferring a Lifetime ISA to their Cash ISA without affecting the annual ISA limit, which I can then transfer back to my HL Stocks and Shares ISA. Once I have tested this I will confirm in an answer
