Having done both kind of work pattern pre-kids, I wouldn’t want to be away from home so much and so regularly regardless of kids. It means everything that needs your input at home, your relationship, seeing friends, socialising as a couple and as a family gets squeezed into a weekend - which is fine if weekends are purely for fun but life doesn’t work that way.
While at the moment you might not see much of the DC, being at home means you’re there if they need you, or if your partner needs support. There’s so much stuff at those ages that kids need a parent there for and which my DH and I split between us so our DC know we both are interested in their lives. I also think at midnight when one child is sick and needs to go to out of hours, I’d want to be around to look after the other two rather than everyone being hauled out of bed. I’d also worry about how isolated my DP would be working from home and caring for 3 DC being home each night would mean we both had options to go for a swim, gym or just to meet someone for coffee (and yes, I’d think the same for a woman in the same position).
£11k is a lot of money, and would be very tempting but I’d rather be at home I think. Different if the kids were older, less reliant, more independent but when they’re still little I’d want to be close to home.
And before anyone trots out “but it would be ok for a man”, in my house it wouldn’t be. We both chose to have children, that meant changes to both our working lives amidst a very long, challenging process to have them - the very least we can do is be physically present.
