2 way to Intermediate?

[Flakey]

Hi there,

I have 2 two way lights that i want to make into a 3 way arrangement.
1 of the 2 way switches is for the downstairs hall light and connects to a 2 way 2 gang switch at the other end of the hallway.
The other 2 way switch is upstairs and lights up the stair case and upstairs hallway. It is also connected the other gang of the 2 way 2 gang switch.
So the cabling is in for the 2 way 2 gang for me to replace with an intermediate switch.

Now the upstairs and downstairs light are on the same circuit but have their own feeds/switch lines to the 1 gang 2 way switches. Im not able to run a cable from the downstairs light to the upstairs light due to the decor flooring etc which would make all lights come on whatever the switch arrangement. Would i for example be able to use the cable in the upstairs switch disconnect the orignal feed core of the cable in the switch upstairs and connect the switch line into L2 for example to light that part of the the circuit simultaneously ( from the first switch downstairs) as the neutral is in the rose upstairs and ive tested for cross neutrals.
Let me know if this allowed if this would work or is there something im missing.
In a Straight forward circumstance where there is access then no problem.

if the feed out of the first light was going straight to the upstairs light then i would use that as my feed i.e feed to switch line across to upstairs light.

Hope its not too confusing or silly to propose!

cheers

No worries Greengardener and for every one who read this as basic stuff there are probably 2 or three who have been helped.

One thing is for sure:

I don't think a gardener should be attempting this kind of work - no matter how supportive of the environment he is....:smilewinkgrin:

Why not??

It's a lighting job so bulbs will be involved somewhere.
