Anyone’s guess really...

Aside from the fact that virtually every jet will behave differently, you could try asking someone with an Eagle Tree Seagull system to mimic exactly the setup they use in failsafe, except manually operate the controls in the same manner. The only assumption is that an engine at idle would closely simulate an engine that's shut down since most guys would avoid shutting down the motor while in 100% control of the model. The seagull system would read out exactly what the velocity, g-loading, and altitude behavior would be in real time... (along with logging the change in trajectory via GPS if you wish!) That would produce some very interesting and valuable data, which I'd like to see if anyone feels like trying it.
