Would you recommend the Artisan Bespoke & topper on the Ottoman?

For the best part of 2 years, my wife and I have been on a mission to find a solution to our transfer of movement problem.
Currently, our mattress is a bog standard king size box spring on a slatted base. So when either of us moves, the movement generated across the whole bed disturbs and wakes the other up.
We have found when staying in nice hotels that there are some beds which seem to eliminate this issue completely. The mattresses are always pocket sprung, and often pilowtops.
Furthermore, from testing in shops we have also found that a solid base makes a huge difference not only to how firm a mattress feels but also to the amount of transfer of movement.
Because my wife gets very hot at night, and also from testing in shops, the memory foam option is out of the question.
But we are hoping the following options will solve our problem:
The option we are leaning towards is therefore an Medium Artisan Bespoke Superking pocket zip&link mattress on a solid ottoman base, and potentially a thick-ish, run cool topper.
We are really hoping this will eliminate at least 90% of the transfer of movement problems we are having.
For context, I am 6’1 and 13 st and my wife is 5’10 and about 11 st. And we are looking for a firm feel.
