Depending on the filesystem, incrementally resizing LVM paritions could be a very _bad_ way to do it - continuously re-sizing a partition will typically encourage poor layout and fragmentation. It would be possible to defragment and optimise the partition afterwards, but that would extend the convertion time even more, especially if it was done in a way which kept a consistent filesystem throughout, on a filesystem without much free space.
The way to avoid, or at least minimise the problem of having one partition filling the disk, is not to fully partition disks to begin with - that gives you the flexibility to test and use different partition types, and move data around. Even without using LVM, it's easy to move data around if it's on partitions which are each no bigger than 25% of the disk.
