AutoCAD .NET :: Process Multiple Drawing Files With Interface Hidden?

I am trying to create a C# program to do batch Title Block attribute updates on selected AutoCAD drawings.

What I would like to do is keep the AutoCAD interface hidden, and just display my custom form which would allow the user to select the drawings that they wish to process.

And then the custom program would load each drawing behind the scenes and update the Title Block attributes, but the AutoCAD interface would remain hidden.

Is something like this possible with AutoCAD 2010?  Are there any examples doing something like this (showing a custom form at startup, etc.)?

PS We do have newer versions of AutoCAD available if needed.  Our engineers use AutoCAD 2010, but we could use a newer version for this standalone tool which would only be used by 1 or 2 people.
