Apart from the health and welfare issues this whole process raises that others have mentioned here - and that ought to be enough to stop you, if you cared:
Your pet insurance - if you have any - won't cover your bitch for anything pregnancy or whelping related. Or the pups.
Some of your 4/5 prospective homes will go cold on you once the pups actually exist (all those allergic children! Those job changes! Those landlords who won't allow pets!), especially as these pups are going to be landing at the most expensive, coldest, darkest, hardest-to-house train time of the year. Around Christmas... In a pandemic.
Raising pups is messy, noisy, smelly, time consuming, expensive, risky, may change your 'amazing pet's' temperament permanently and in this case it's totally unnecessary. They will be with you for a minimum of eight weeks while you trot backwards and forwards to the vet for worming meds, microchipping and if they stay longer than the minimum you'll be looking at vaccinations too. They may have complex genetic disorders you have no way of knowing about because you haven't tested for them.
Good plan, OP. Good plan. Especially now.
There's a thing called misalliance treatment. You should look into that. Then get the bitch spayed.
