This question is pretty similar to this one but you provide a slightly different position so there may be some variances. Some things to consider,
- In the F1 like case, blood would still have the ability to pool in the gluteal region as well as the feet since they are lower than the head.
- In the more reclined, feet forward position one would need to have the instrument panel over their legs (and a significant amount of it) lest it be quite far and possibly out of reach. This could potential cause a problem in an ejection scenario.
A good, practical example of this position is the Bede Jet a not so popular kit plane famously flown by James Bond.
