Why would the ideal place be in the city centre?
If you consider Nottingham Victoria then it really is central to Nottingham. Anybody wishing to use the service would need to get into the centre and then catch thier train. Anybody coming to Nottingham would arrive in the center.
But Nottingham is really quite small and the city itself wouldn't provide the demand for a dedicated HS link. To get the numbers you need to look to it providing a service for a whole region.
How long would it take to get to Nottingham city centre from Derby? From Leicester? From the airport? From Mansfield/Chesterfield, etc, etc... How would people do this? By public transport?
It is most likely that people will choose to drive short to moderate distance to the rail station and then take the train. HS stations need to be in the middle of BIG cities (London, Birmingham, Manchester, Glasgow and Edinburgh) but elsewhere will need great access for cars.
If a HS station is built at Toton it will be a reasonable taxi trip from Nottingham AND Derby as well as East Midlands Airport. If it were in the city centre then it would be longer to travel to anywhere other than Nottingham city centre.
This seems to be the method already employed by planners. Ebsfleet doesn't serve a massive city - it does though have a massive car park which is easy(ish) to get to from a large area.

Well, what I was assuming was the classic station model. People arrive by public transport (bus and tram in Nottingham - taxi for some) then catch their train onwards. This happens anyway. To get to an out-of-town station, you would need to add an extra stage to this, the connecting train/tram(/underground) trip to the station. It would also encourage car use as an alternative, or very long taxi rides.
We have several examples of this in airports. The journey to the airport is a significant factor in time and money. It might be less of a problem for departing passengers, but
arriving passengers, who don't have a car available, tend to find the extra trip into the city centre a major problem. Think about where you want to
go rather than where you want to start from, and then imagine arriving at LGV Interconnexion Est rather than Gare do Nord.
Of course, you have to add in the journeys from Derby, Leicester, Loughborough, Ruddington, etc. These people would have to make a connecting journey anyway, if they did not travel by MML in the first place. In terms of accessing Victoria, they have the added problem of an inter-station transfer (you could divert the former Great Northern lines into Victoria [which would help people from Grantham etc.] but not the Midland lines). It's possible to get round, since the distance is not that far, and trams could carry the majority of passengers.
HS2 slow lines could feed in passengers from the north as well. The Norwich-Liverpool route could run via both Victorias (Nottingham and Sheffield) then over the Woodhead to Manchester (or the old line if they don't rebuild it). Then, some Cross-Country services could feed in via the other side of the Great Central from Leicester. However, Burton-on-Trent, Derby and Chesterfield would lose out. Still, the benefits of plugging HS2 into the rest of the network would probably outweigh the losses.
The real message is that you can't please all of the people all of the time.
