I am trying to fly as many segments over a weekend as I can to secure my RJ platinum hawk status. I've put together the below itinerary which is not without its risks but I just want to check if there's any obvious showstoppers that I'm missing.

Each black box is a separate ticket so I'm somewhat protected in case of IRROPS within the 4 sectors in each ticket, but it can obviously have knock-on impacts on the next ticket which would be unprotected. I am not familiar with most of these airports but the fact that IB is willing to sell 40 min turn-arounds suggests to me you would disembark airside and board the flight from the same gate without needing to go landside.

I realise its going to be gruelling weekend and there's a real chance that I end up missing connections in case of delays or schedule changes. But is there anything here that is likely not going to work even if the flights run on time? E.g. 1h25m turnaround at MAD on the Saturday evening or the <2h connection from the BA flight to IB (which would require transfer from T4S to T4) or any of the 'destination' airports not being suitable for a back to back turnaround on to the inbound aircraft?
