As far as I'm concerned, say something sooner rather than later and we'll accomodate it.
My only concern would be that it doesn't become a regular request from multiple aircraft. Because if it does, landing rates will go down, EAT's will go up, and you'll be off to Gatwick before you even make it anywhere near BOV
WF.
p.s. the minimum spacing isn't for HAL's or ATC's benefit, it's for yours and ultimately your company's in order to minimise overall delays.
