Widening existing block paving driveway

[rh2205]

The entrance to our driveway is too narrow but quite long, we have decided to pull up a section near the double garage for some additional borders to screen this incase we convert at some point & widen the width of the driveway over an existing flower bed using our reclaimed pavers so we can properly have two cars parked side by side (or 4 cars if double stack).
 

What’s the most simple way to do this? When we have gone to companies nobody wants to touch a half job they just want to rip it all up and start again, I don’t particularly want to pay the labour either or what will be quite high material costs if we are starting from scratch and maybe having to lay a whole new sub base. I don’t think the original driveway had any actual MOT laid but other than few very minor dips it doesn’t seem to of moved, looks like they put in a soldier course on one side. It’s a fairly old driveway with 100mm thick highway spec blocks. Will it be that hard to lay some MOT and compact an area next to the current entrance and extend it out using the same reclaimed paving, or is this a bad idea?

Not an awful idea but edge restraint is critical, and that restraint must hold the sub-base and the grit-sand, not just the blocks, otherwise the sand just runs out and the blocks droop.
