Hello please don't shoot me down its my first ever DIY post/question online. Recently updated upstairs to new regulation cables

The problem I have is at the hallway light. It's a 1 gang 2 way switch. The cables that come from downstairs are the old rubber ones. 2 of the them. They were in l1 and l2 on the previous switch.

So I have now at the switch ended up with a twin brown (Coming from the hallway light live and switched live) and 2 cables from the downstairs switch. Is there anyway to connect it so I can switch the upstairs hallway light on from downstairs again. Will just temporarily untill I get the downstairs cabling done.

Another option is to make the light wireless but did not want to bury the transmitter underneath the loft boards only to lift up again to change it back.

I understand there might be a transmitter I can put in the downstairs back box to transmit to the upstairs switch.

Thank you, any advice is appreciated. Have tried to post a pic up no luck loading.
