It's not quite as simple as all that. If the two packs are rated the same, such as...
2s2p 5000mAh 20c
2s1p 5000mAh 20c
You will not have a higher current rating from the 2s2p pack. The 2s2p pack will be composed of 4 2500mAh cells, while the 2s1p pack will be composed of 2 5000mAh cells.
I would also add that you have twice the likelihood of a cell failure in a 2P pack versus a 1P pack.
