New sink & waste pipe position - help

I feel I may have majorly cocked up with my planning here.

I am looking to replace my bathroom sink, because over time it's proven to be too small for our requirement. The one I am replacing it with is a rectangular shape and therefore has a much larger area. It is also approx. 3cm wider than the current one.

In addition, I also want to remove the empty pillar on the right of the sink (approx. 8cm wide) - and then I want the sink to shift to the right, so there is no gap with the wall.

What I have failed to take in to account is the current location of the waste pipe. With the sink moving across, the pedestal will cover the existing hole and a new hole will need to be created.

I don't think that's impossible, as I suspect you would need to remove the back tiles, and add a joint to move the pipe about 6-7 cm along the floor and then replace those tiles. The problem I have with this is that I cannot for the life of me find that particular tile. It's 33cm x 33cm and is like a very light grey. The closest one I could find is this: https://www.diy.com/departments/mon...ck-of-13-l-333mm-w-333mm/3663602608011_BQ.prd, but after putting it against the current tiles, it's more white than grey and the difference is going to be visible right away.

I know I will need to add a small tile on the floor where the pillar is, but I'm not too bothered about that as I plan to put the wastebin there - so it won't be visible anyway. I don't want to replace the entire flooring as that would turn a relatively cheap job in to an expensive one.

What are my options here? I really don't want to keep that pillar and even if I have to, the new sink will almost - if not - be touching the toilet cistern.

Sometimes spare tiles are left behind kitchen plinths. That's where mine are...

It's not ideal but you could run waste to toilet pan connector

Matching tiles is a problem if you don't have any
 
Maybe swap to a vanity unit? Are you sure that pillar is empty? Could have pipes hidden?
