There is an option in 3dDeconvolve, called -local_times, with which you can specify each run's stimuli in local times.

By t-maps do you mean that you average the t-statistic or beta value across runs? It should be the beta values that get averaged. However if you want to take the correlation coefficients for group analysis, it's not a good idea to average them either.

Yes, it should be more or less close to the alternative approach.
