It really doesn't seem possible. I wonder how they dealt with the fire safety issue? I didn't think intumescent paint would be enough to get exposed steel supporting an entire tower past engineering and fire safety requirements. One of those legs fails and the whole tower comes down taking the neighbouring building with it.
The steel support is hollow - it will be filled with concrete. Besides if you look at the plans it isn't the only structural support - as important as they are, there are a series of columns in the heritage building as well.
