Hi yes, if you have feed twin &earth plus 3 core &earth to each sw. then just disconnect 3 core/e from light to pull switch totally & remove sw. & if poss cable so no confusion later.
At wall sw. you should find red in common, leave it there, find which colour in L1 (yel. or blu.), mark it as red ie tape/sleeve. disconnect other wire from L2, cut bared end off and make safe in conn.block, at light move L1 core to position vacated by red from pull sw., also tape/sleeve as red sw.live.
hope this makes sense, regards SPARX
