Yes, your situation will be the same once the season starts. Your only way out if you want to make any moves is to shed the 2m in a trade (might take a while to find a willing trade partner) or to lose some salary by releasing players. Honestly though, most teams I see this happen to end up keeping their team throughout the season and often earn back promotion as their players are that much better than everybody else - that said, I've also watched some spectacular relegations for other teams in the same situation.
 
Also, this should be in questions. 

Well honestly I was also already thinking about this and I don't think it would be bad idea. However it should be made like in NHL IL. If you put a player on the list he has to be there for at least 7 days. So basically it would be only for medium/longer term injuries which I think is right. Or allow put on the list players injured for 7+ days only. 

The gap in Biscuit isn't as big as you state but it still is very noticeable.
 
The reason why I asked if just adjusting the talent gap would be enough is because it logically doesn't make sense to have the other promotion/relegation playoffs be one way and have the GHL/SHL one different. Especially if the talent gap largely goes away. Also as you say the talent gap is the reason for you posting then if it is fixed your reasoning for the playoff change (besides just wanting something different) goes away too does it not?
 
Finally I am indifferent to your idea as, even though I see the good and bad, I just don't see it as an improvement. Chiefly because it just makes things unnecessarily more complicated to have 2 different promotion/relegation systems at play at the same time.
 
I do think that at least 2 teams should promote automatically with the current system. I played a game where only one team promoted each year (with no fight for a 2nd spot) which made it very frustrating just to finish second repeatedly. However I would think it better that 2 more teams have the chance to demote rather than a chance and another forced demotion. Once a GHL league gets filled with human players and there are no outstanding teams benefiting from a history of AI trade abuse the margin of error becomes rather small to the point where an injury plagued season can see a regular strong playoff team finish in the bottom 5. That said I do not think that we currently have the best possible system in place in terms of making promotion/relegation fun and fair all around. I do believe that we have the best in terms of simplicity which from Anders perspective coding wise is much more important.
 
Personally I think that once Anders gets rid of the skill gap between the SHL and GHL you will find the system to be perfectly fine.
