The tank input and pressure switch should be close together, so the pressure switch and pressure tank feel the almost same pressure. Your change would be going the other way on that. As there is more separation with the pressure switch being closer to the incoming water, the pressure switch will tend to turn off before the pressure tank gets to the desired turn-off pressure.
If you decided to lengthen the path anyway, doing as much as you can with 1-1/4 rather than 1 inch, would minimize the drop for a given length.
That riser for the pressure gauge and pressure switch doesn't count because there is no flow, so no pressure drop. If you could move that riser over close to the new tank input, that would be good. That riser can be useful to prevent sediment from clogging the pressure switch or pressure gauge.
